Broken Finger or Thumb

A broken finger or thumb, also known as a fracture, occurs when one of the bones in the finger or thumb breaks. This can happen due to various reasons such as a fall, direct blow, or sudden twisting motion.

Types of Fractures

  • Non-displaced fracture: The bone remains aligned and does not require reduction.
  • Displaced fracture: The bone is out of place and requires reduction to restore proper alignment.
  • Comminuted fracture: The bone breaks into multiple fragments.
  • Open fracture: The skin is broken, and the bone is exposed, increasing the risk of infection.

Symptoms

  • Pain or tenderness in the affected finger or thumb
  • Swelling or bruising
  • Difficulty moving the finger or thumb
  • Deformity or abnormal alignment of the finger or thumb
  • Numbness or tingling sensation

Diagnosis

Diagnosis is typically made through a combination of:

  • Physical examination
  • X-rays to confirm the fracture and assess its severity
  • CT or MRI scans may be ordered in complex cases

Treatment

Treatment depends on the type and severity of the fracture:

  • Immobilization: A splint, cast, or buddy taping to immobilize the finger or thumb and allow it to heal.
  • Pain management: Over-the-counter pain medications such as acetaminophen or ibuprofen.
  • Reduction: A medical professional may need to manually realign the bone fragments.
  • Surgery: May be necessary for complex fractures, open fractures, or if the fracture does not heal properly.

Recovery and Rehabilitation

The recovery time for a broken finger or thumb varies depending on the severity of the fracture:

  • Mild fractures: 3-6 weeks
  • More severe fractures: 6-12 weeks or longer

Rehabilitation may include physical therapy to regain strength, flexibility, and range of motion in the affected finger or thumb.

Complications

  • Infection
  • Nerve damage
  • Avascular necrosis (death of bone tissue due to lack of blood supply)
  • Malunion or nonunion of the fracture

Prevention

To reduce the risk of breaking a finger or thumb:

  • Wear protective gear during sports and activities
  • Avoid falls by using handrails and being mindful of surroundings
  • Maintain strong bones through a balanced diet and regular exercise
